In the European Union (EU), mandatory durability ecodesign requirements have recently been set for vacuum cleaners and lighting products. Durability standards for additional product groups are expected in the future and it is also envisioned that durability issues will be integrated in the EU energy labelling scheme. Durability standards can bring environmental benefits, but there are several meth
Biogeochemical cycling of elements largely occurs in dissolved state, but many elements may also be bound to natural nanoparticles (NNP, 1-100 nm) and fine colloids (100-450 nm). We examined the hypothesis that the size and composition of stream water NNP and colloids vary systematically across Europe. To test this hypothesis, 96 stream water samples were simultaneously collected in 26 forested he
Detta examensarbete undersöker tjänsteleverantörers roll vid insamling och bevarande av elektroniska bevis, och huruvida förordning (EU) 2023/1543:s tillämpning innebär en ökad privatisering av brottsbekämpningen. Uppsatsens övergripande syfte är att illustrera tjänsteleverantörers roll vid insamling och bevarande av elektroniska bevis. De tjänsteleverantörer som är föremål för undersökning har avThis thesis examines the role of service providers in the production and preservation of electronic evidence and whether the application of Regulation (EU) 2023/1543 will lead to an increased privatisation of law enforcement. The overall aim of the paper is to illustrate the role of service providers in this process. The service providers subject to examination are delimited to electronic communic
Many songbird species that breed at northern latitudes migrate long distances each autumn, while others brave the cold winter. Long-distance migrants have physiological adaptations that allow them to rapidly gain weight at stopover sites during migration for optimal speed. There is some evidence from closely related species that birds with a longer migration distance deposit fuel faster. However,
The aim of this study was to examine whether visitors to family counseling intended to go to one or more sessions of counseling and whether the expectations and experiences of the first session affect the visitors intention. It was a quantitative study that consisted of two parts, a survey and a structured interview. The participants in the survey answered the survey before their first counseling
High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. In this study, an arctic-enabled version of the LPJ-GUESS dynam
In the following study, the aim has been to create an understanding of what social workers think about an evidence based practice and in which way they mean that this affect social work as a profession. We conducted semistructured interviews with seven socialworkers, working with children and families in three different municipalities. The result of the study has been discussed in relation to form
Efforts to reduce energy consumption in buildings have increased with the pending impact of climate change. Heat losses through airing behaviours remain a largely unknown factor due to the variety of reasons for opening a window, making generalization difficult. Currently, an estimation of 4 kWh/m2 heated area for airing heat loss is assumed in Sweden. Additionally, the resulting airflow from open
In this master’s thesis, a novel unsupervised anomaly detection tool was developed in collaboration with Sandvik Rock Processing to assist engineers and experts in analyzing large amounts of sensor data from cone crushers used in the stone crushing industry. The tool focuses on analyzing power, pressure, and CSS sensor data. A crucial preprocessing step was implemented to algorithmically identify
Phytoplankton and zooplankton interactions are vital in regulating nutrient cycles and productivity in aquatic ecosystems. Nevertheless, zooplankton account for the majority of phytoplankton mortality in the ocean. Due to predation pressures, phytoplankton have evolved several defensive traits, many of them being inducible defenses such as toxin production, colony size alterations, swimming behavi
The aim of this study has been to distinguish how the social workers make decisions on which activations program that the client is demanded to participate, in relation to their eligibility for social assistance. Eight social workers in four different municipalities working within the field participated this study. They participated in a semi-structured interview as well as vignettes. The study sh
Accidents occur in the society daily which require the fire service to respond. The fires cause socio-economic cost estimated to the equivalent value of 7 billion SEK every year. One of the strategies used by the municipalities to reduce the effects of the accidents is to investigate the fires to be able to prevent similar fires in the future. Recent research suggests that the investigations needs
This master thesis has been conducted at the Division of Combustion Engines under the Department of Energy Sciences, Faculty of Engineering at the Lund University. The purpose of this master thesis project is to create a computer based model of a Natural Gas Engine in order to raise its potential for updating a Volvo bus as well as creating a study of the improvement efficiency of the Miller Cycle
Uppsatsen undersöker och granskar hur gällande rätt, inom sakrätten reglerar och präglar användandet av säkerhetsöverlåtelser som kreditsäkerhet. Därutöver undersöks även det avtalsförhållande som långivaren och låntagaren befinner sig i när äganderätten, gällande säkerhetsobjektet, övergått till långivaren. Även nyttjande- och separationsrätten diskuteras och undersöks i förhållande till hur rättThe paper examines and reviews how the current right of rem regulates and characterizes the use of security transfers as credit security. In addition, the contractual relationship that the lender and the borrower find themselves in when the ownership of the collateral has been transferred to the lender is also examined. The right of use and separation is also discussed and examined in relation to
BACKGROUND: Systematic comparisons of mode of inheritance for renal cell carcinoma (RCC) have not been carried out. The occurrence of cancer in parents and offspring may be due to dominant causes, whereas cancer affecting only siblings may indicate a recessive causation. Environmental effects need to be excluded.METHODS: The Swedish Family-Cancer Database includes all Swedes born after 1931 with t
Familial risks for cancer are important for clinical counseling and understanding cancer etiology. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0 to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Urological cancer cases were retrieved from the Swedish Cancer Registry up to year 2000. Standardized incidence ratios (SIR
Flavin-dependent halogenases regioselectively introduce halide substituents into electron-rich substrates under mild reaction conditions. For the enzyme Xcc4156 from Xanthomonas campestris, the structure of a complex with the cofactor flavin adenine dinucleotide (FAD) and a bromide ion would be of particular interest as this enzyme exclusively brominates model substrates in vitro. Apo Xcc4156 crys
The road safety barriers are today designed and installed in compliance with the European standards for Road Restraint Systems (EN 1317), which lays down common requirements for the testing and certification in all EU countries. The introduction of the European Union (EU) regulation for safety barriers, which is based on performance, has encouraged European road agencies to perform an upgrade of t
